Abstract:
A device comprises a memory and a processor. The memory stores an image. The image includes a plurality of areas. The image is captured using at least one of an auto-exposure technology and an auto-focus technology. The processor is coupled to the memory and selects at least one of the plurality of areas as a function of predetermined data. The data is related to the at least one of the auto-exposure technology and the auto-focus technology. The processor locates a symbol in the at least one selected areas.
Abstract:
Methods and apparatus for improving direct part mark dataform decoding using a scanner comprising a processing unit, an optical module and an imaging sensor with an extended dynamic range. The scanner captures data to obtain an extended dynamic range image for analysis. In one embodiment, the sensor is sensitive to more than eight bits per pixel and in other embodiments multiple exposures are taken. Further in alternate embodiments, the scanner comprises a pass-band filter that passes the light emitted by an illumination module.
Abstract:
A linear sensor array for imaging coded indicia includes an analog front end (12) and a digital back end (14) integrated on a single CMOS chip (10). An analog to digital converter (22) is provided. A real-time, correlated double sampling circuit (26) is used for noise suppression.
Abstract:
A subarray (52, 54 56, 58) of a CMOS imaging sensor array is addressed to detect when a target symbol is fully within a field of view (44) of an imaging reader to improve reader performance at high swipe speeds.
